    Taskcluster Documentation Tool

    Build Status npm License

    A simple library to allow all of our libraries and services to update their own documentation automatically upon publish or deploy.


    View the changelog on the releases page.


    This is tested on and should run on any of node {7, 8}.


    The library works by creating a tarball full of documentation when the production service starts up. The tarball contains a mixture of documentation from the project's README, auto-generated documentation for pulse exchanges and APIs, and hand-written documentation.

    The taskcluster-docs project then downloads those tarballs and incorporates the results into the documentation page.

    Documentation Tarball Format

    The format for the tarball that is uploaded to s3 is documented here.

    Usage in Services

    Do not forget to add the scopes before pushing your service to production! [auth:aws-s3:read-write:taskcluster-raw-docs/<project>/]

    This library should be included as a component in a Taskcluster Component Loader setup so that it is called upon a service starting in Heroku or as a post-publish step in a library. Options and defaults are listed below.

    This will automatically take any markdown files in a top-level docs/ directory and turn them into rendered pages on the docs site. A top-level will be uploaded automatically. In addition, any schemas and references can be passed in, and they'll be turned into documentation as well.


    let docs              = require('taskcluster-lib-docs');
    let v1                = require('./v1')  # the API declaration
    let config            = require('typed-env-config')
    let validator         = require('taskcluster-lib-validate')
    let load = loader({
      cfg: {
        requires: ['profile'],
        setup: ({profile}) => config({profile}),
      validator: {
        requires: ['cfg'],
        setup: ({cfg}) => validator({
          prefix: 'service/v1/',
      reference: {
        requires: ['cfg'],
        setup: ({cfg}) => exchanges.reference({
          credentials:      cfg.pulse,
      docs: {
        requires: ['cfg', 'validator', 'reference'],
        setup: ({cfg, validator, reference}) => docs.documenter({
          credentials: cfg.taskcluster.credentials,
          tier: 'core',
          schemas: validator.schemas,
          references: [
              name: 'api',
              reference: v1.reference({baseUrl: cfg.server.publicUrl + '/v1'}),
            }, {
              name: 'events',
              reference: reference,
      // the server component should depend on `docs` so that it is loaded, but
      // doesn't actually do anything withe value
      server: {
        requires: ['docs'],
        setup: ({docs}) => {
          // ...
    }, ['profile', 'process']);

    Options and Defaults

    The following are the options that can be passed to the publisher function in this library. They are listed with their defaults.

        // A set of Taskcluster credentials. The client must have scope
        // `auth:aws-s3:read-write:taskcluster-raw-docs/<project>/`. Don't forget the
        // trailing slash! Credentials can be omitted if the authBaseUrl points to a
        // proxy that will add credentials.
        credentials: {},
        // The base URL for the auth service.  This can be useful when running in a task with access
        // to a taskclusterProxy
        authBaseUrl: undefined,
        // The name of the project will automatically be set to your package name from package.json,
        // but can be overridden if needed.
        project: '<name of project in package.json>',
        // The path to the file for the project
        readme: '<project root>/',
        // This must be set to the project's tier, corresponding to the section of the docs reference
        // chapter that this will appear in. Options include 'platform', 'core', 'integrations', 'operations',
        // 'libraries', and 'workers'.
        tier: null,
        // This should be set to the value of the schemas field from an instance of taskcluster-lib-validate.
        // It provides the schemas necessary to generate the api and events references.
        schemas: {},
        // Optionally help taskcluster-docs pick the order this documetation should appear in on the list.
        menuIndex: 10,
        // If your documentation is in any directory other than '/docs', set this manually.
        docsFolder: rootdir.get() + '/docs',
        // This can be specified as follows:
        // references: [
        //   {name: "api", reference: api.reference},
        //   {name: "events", reference: exchanges.reference},
        // ],
        references: [],
        // Whether or not the generated documentation should be uploaded to s3.  Generally services will only
        // upload in production.
        publish: process.env.NODE_ENV == 'production',
        // A set of aws credentials that allows you to use this library directly. Must contain both 'accessKeyId'
        // and 'secretAccessKey'.  This is only required if credentials is unavailable.
        aws: null,

    Development & Testing

    This library requires a set of Taskcluster credentials to test. Copy user-config-example.yml over to user-config.yml and follow the instructions within to get set up.

    Once that is complete, yarn install and yarn test. You can set DEBUG=taskcluster-lib-docs,test if you want to see what's going on.

    To release, run yarn version [major, minor, patch] (following semver) and push to master. Travis will take care of the rest. Generally this change is not included in the PR.
